Interlock Assa Abloy Lever Compression Locks for Aluminum and Vinyl Doors

The Interlock multipoint lock line from Assa Abloy represents a specialized category of lever compression hardware engineered specifically for aluminum and PVC door systems. These locks utilize a distinctive swing deadbolt mechanism that differentiates them from standard European-style multipoint systems. MPLocks carries a focused selection of Interlock mortise lock cases and lever handles to support both new installations and replacement scenarios where original Interlock hardware needs to be matched precisely.

Compression Lock Design for Enhanced Weather Sealing

Interlock lever compression locks feature an innovative swing bolt design where the deadbolt swings upward when the handle is lifted, simultaneously extending the shootbolts while converting the spring latch into an additional locking point. This compression action pulls the door tightly against the weatherstripping, creating a superior seal against air and water infiltration. The high corrosion-resistant construction makes these locks particularly well-suited for coastal environments and applications where aluminum doors face exposure to the elements.

Flexible Configuration Options for Multiple Door Types

These Interlock mortise locks offer versatile installation options, functioning as single-point locks or expanding to 4-point systems when paired with concealed rods. Available backset sizes include 30mm, 35mm, 40mm, and 50mm to accommodate different door profiles and frame depths. The lever handles are non-handed for simplified inventory and installation, and the single-motion activation provides convenient operation while engaging all locking points for maximum security.

Understanding PZ Measurements for Interlock Hardware

When selecting replacement Interlock hardware, the PZ measurement—the distance from the handle center to the cylinder center—is critical for proper fit. Interlock locks are available in either 85mm or 92mm PZ configurations, and this dimension must match your existing door preparation. The backset measurement, ranging from 30mm to 50mm depending on the model, determines how far the lock mechanism sits from the door edge. Before ordering, measure your current lock's backset and PZ dimensions to ensure compatibility with these Assa Abloy compression lock systems.
